Validation of PBF Figure of Merit Calculational Techniques Using Non-Calorimetric Measured Data

摘要

The accuracy of the calculational techniques used for routine predictions of test fuel power levels in the PBF is investigated by comparing flux-wire activation and direct fission density measurements obtained during selected PBF experiments with corresponding calculated results generated using standard PBF reactor physics calculational models. It is concluded from the three tests examined that in some cases the standard calculational methods can tend to systematically overpredict test fuel powers by as much as, but in all probability no more than, approximately 12%.
